3 Claims. (Cl. 183-51) The present invention relates to dust receptaclesand more particularly to attaching the receptacle to a suction cleanerand closing the inlet to the receptacle to seal the dust therein priorto discarding the receptacle.

An object of the invention is to provide a disposable paper dustreceptacle for a suction cleaner. Another object is to provide a dustreceptacle having an adhesive for removably attaching the receptacle toa cleaner. A further object is to provide a dust receptacle having anadhesive for removably connecting the aperture in the receptacle withthe inlet of a suction cleaner. Still another object is to provide aseal for the inlet aperture in a dust receptacle to prevent escape ofcollected dirt upon removing the receptacle from a cleaner. A furtherobject is to provide a dust filtering receptacle having an adhesive forremovably attaching the receptacle to the cleaner and also for sealingthe inlet aperture in the receptacle prior to discarding the latter.Other objects and advantages of the invention will become apparent fromthe following description and drawings wherein:

Figure 1 is a section along the line 1-1 of Figure 2 showing the suctionend of a cleaner casing,

Figure 2 is a section along the line 2-2 of Figure 1,

Figure 3 is a perspective view of the dust receptacle with the inletclosed, and

Figure 4 is a perspective view of the dust receptacle showing the inletuncovered for insertion in the cleaner casing.

The embodiment of the invention herein disclosed comprises a dustreceptacle arranged within a cleaner casing 11, only partly shown,provided with supporting skids 12 and an unshown suction creatingmotor-fan unit. At the front end of the casing 11 is an L-shaped annularmember 13 attached by screws 14 to the casing and having an end flange15 projecting inwardly of the casing and defining an opening 16 forinserting the bag 19 into the casing 11. An end cap 17 is hinged at 18to the casing 11 and has spaced inner and outer walls 19-20respectively, and a tubular member 21 extends between the walls and isprovided with an inner end 22 projecting inwardly of the casing flange15 into ,a chamber 23 occupied by the bag 10. The outer end of the tube21 has a flanged collar 24 which receivesv one end of an unshown hoseprovided with a suitable surface cleaning nozzle for conveyingdirt-laden air into the bag 10. A clamp 25 is mounted on the casing 11and has an end 26 engaging the end cap 17 to lock the latter to thecasing.

The bag 10 has a rectangular portion 27 formed of filter paper to removethe dirt from the incoming dirtladen air stream and includes oppositewalls 28, side walls 29, a bottom wall30, and a top wall or end plate31. The top wall 31 is of relatively stiff material and is glued to anannular exterior flange 32 on the bag, and has a marginal flange 33projecting beyond the walls of the bag 10.

The bag 10 is secured within the chamber 23 by an 2,823,761 PatentedFeb. 18, 1958 annular resilient member 34 mounted in a recess 35 or thecover inner wall 19 and bears against the bag flange 33 to seat thelatter against the casing flange 15 when the cover 17 is locked in placeby the clamp25. The walls 28, 29 and 30 of the bag 10 are flexible andlined to be folded flat with the end plate 33 folded along a side wallof the bag for ease in storing and packaging.

Disposed centrally of the end plate 31 is an inlet aperture 36 whichreceives the inner end 22 ofthe inlet tube 21 to convey dirt-laden airinto the bag 1.0. The exterior surface of the end plate 31 adjacent theaperture 36 is provided with a pressure sensitive adhesive or gummedsurface 38 between thelines 39 and 40 as shown in Figures 3 and 4. Theexterior surface of the end plate 31 is covered with a paper sheet 42having spaced scored lines 43--43 for removing a tape portion 44 whichnormally covers the adhesive area 38 around the bag aperture 36. Inorder to uncover the aperture 36 the end 45 of the tape 44 is grasped bythe operator to tear the tape 44 along the lines 4343 to the line 46 asshown in Figure 4. When the tape 44 is peeled back as in Figure 4 theadhesive area 38 is exposed and is adapted to receive a surface 46 of asealing ring 47 on the cover wall 19 about the tubular end 22 to providean air tight seal between the bag aperture 36 and the inlet tube 21.

When it is desired to place the bag 11 in the cleaner casing the clamp25 is unlatched and the cover 17 is rotated about the hinge 18 to itsopen position to expose the casing flange 15. The end 45 of the tape 44is then grasped by the operator to tear the tape 44 along the lines43-43 to the position shown in Figure 4 to thereby uncover the bagaperture 36 and the adhesive area 38. The bag is then inserted in thechamber 23 with the flange 33 resting on the casing flange 15, and thepeeled portion of the tape 44 is arranged between the bag wall and thecasing wall as indicated at 48 in Figure 1. Upon pivoting the cover 17to its closed position the tubular end 22 passes through the bagaperture 36 into the bag and the surface 46 of the resilient sealingmember 47 bears against the tacky surface 38 on the mounting plate 31 toprevent passage of air between the exterior of the tube 22 and theaperture 36. The resilient member 34 also bears against the bag flange33 to secure the bag within the casing 11. Thereafter a hose is attachedto the collar 24 and dirt-laden air is conveyed to the bag 10 whichseparates and collects the dust from the air stream. a

When the bag 10 must be replaced the cover 17 is pivoted to its openposition and during such movement the resilient locking member 34releases the bag supporting flange 33 from the casing flange 15 whilethe sealing ring 47 remains attached to the bag so that the latter ismoved partly through the opening 16 while the cover 17 is being shiftedto its open position. The operator then grasps the peripheral edge 50 ofthe bag end plate 31 and pulls the adhesive surface 38 away from thesealing ring 47 to disconnect the bag from the cover 17 and permitcomplete removal of the bag from the casing 11. The sealing tape 44 isthen replaced along the lines 43-43 to cover the aperture 36 and preventescape of dirt, thereafter the bag can be carried to i a waste basket ordestroyed without danger of the dirt leaking from the bag.

While I have shown and described but one embodiment of my invention, itis to be understood that this embodiment is to be taken as illustrativeonly and not in a limiting sense. I do not wish to be limited to theparticular structure shown and described but to include all equivalentvariations except as limited by the scope of the claims.
